PHP three-dimensional array to two-dimensional array

$result = Array(0 => Array(0 => Array(bid => 41,brealname => 'we instructor',cid => 41,crealname => 'we instructor ')),
1 => Array(0 => Array(bid => 6,brealname => 'Huzi',cid => 19,crealname => 'Zhangyu'))

);
//Original array
print_r($result);
echo "
";
//First method:
foreach ($result as $key =>$v){
$ new_arr[]=$v[0];
}
echo '

';
print_r($new_arr);
//Second method
//Initialize $arr2 
$arr2=array(); 
 
//Loop through the three-dimensional array $arr3 
foreach($result as $value){ 
  foreach($value as $v){ 
           $arr2[]=$v; 
   }   
}
//Destroy $arr3 
unset ($result,$value,$v);
echo "
";
echo "Second method:";
echo '
';
print_r($arr2);
? 
?>
                
                
                


                    The above has introduced the conversion of three-dimensional arrays into two-dimensional arrays in PHP, including all aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
